TRACK JACK.

Application filed December 18, 1926. a Serial No. 155,686.

This invention relates to track jacks and has for a particular object thereof the provision of a device of this character which may be conveniently employed in aligning and leveling rails, removing and replacing ties and the like. I

A further object of the invention is to rovide a device of this character so constructed that it may be readily connected with the available fixed points present in railway track structures to enable the shifting of the elements thereof, as required.

A further object of the invention is to provide a device of this character which may be employed either as an ordinary jack or as a jack for pulling elements which are to be shifted.

These and other objects I attain by the construction shown in the accompanying drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention and wherein c Figure 1 is a side elevation showing a track jack constructed in accordance with my invention applied to remove a tie from beneath the rail;

Figure 2 is a similar view showing the jack as appliedv to shift a tie longitudinally of the rails and illustrating the use of the rail grip;

Figure 3 is a of the rail grip;

Figure 4- is a fragmentary plan showing the plate employed for embracing the end of the tie in the use of the jack as shown in Figure 1;

Figure 5 is a fragmentary side elevation of the jack, the base thereof being indicated in dotted lines;

Figure 6- is a side elevation of the base partially broken away to show the opening for the passage of the rack bar and chain hook;

Figure 7 is an enlarged section on the line 7-7 of Figure 5. 1

Referring now more particularly to the drawings, the numeral 10 generally designates 'the housing of the jack structure which in accordance with my invention, is formed in upper and base sections 10 and 10 separable from one another; In the fragmentary side elevation preferred construction of the housing, the base. section is provided at its upper end with enlargement 11 forming a socket receivmg the lower end of the upper casing sec; tion and to which the upper casing section may be held by means of a removable pin This lower base section is provided with a handle 13 extending therefrom at the same side of the base structure as the lever socket 14: of the upper structure, so: that at this side of, the jack, upper and lower hand holds are provided, enabling the jack to be readily placed in adesired position. The controlling structure 15 employed with the jack may be of any ordinary jack structure. The upper casing section at the opposite side thereof from the lever socket 1 1 is provided with a right angular extension 16 having at the extremity thereof and upon that face directed toward the base end of the jack a lug or prong 17, which is adapted to engage in an end or side face of a tie and prevent the jack from slipping therefrom. That face of the upper sect-ion of the jack casing under-lying the tie hook 16 has its lower end vertically slotted, as at 18, and the corresponding side face of the base section 10,? is similarly slotted at 19. The base 20 of the base section 10 has an opening 21 formed in its bottom. The rack bar 22 which is employed is considerably longer than that ordinarily employed on such jacks and has formed upon its lower end a flattened chain hook 523, the bill 2e1- of which extends through the slots 18 and 19 and may be projected through the opening 21. The head end of the rack bar has applied thereto a head 2-5,- which is providedwith a deep central notch 26. I 4

In combination with a jack structure of this-character, I provide a rail grip comprising a relatively heavy metallic body 27 having formed therein in one face thereof a transverse slot 28 adapted to receive the head H of a rail. To this body at one end is connected a relatively heavy chain 29-. I also employ what may be called a tie plate, generally designated at 30, this plate being adapted to engage one end of a tie and having openings adjacent its opposite side edges, one of which receives one end of a chain '31 and the opposite end of which receives a hook bolt 32 receiving a link of the opposite end of the chain 31.

In employing the jack for lifting rails, the jack is placed with its base beneath the rail and the bill 24-of the hook underlying the rail. The rail is thenlifted by manipulating the jack in the usual manner. When it is desired to space ties, two jacks are employed, one at each end of the tie, The bases of the jacks are removed and rail grips R engaged with the rails at points properly spaced from the tie in the direction in which it is to be moved. Thetiehooks of the jacks are then engaged with the face of the tie remote fromithe rail grips andthe hooks 23'of the jacks engaged with" the chain of the rail grips. It will be obvious that 'as tension is applied by manipulation of the jack, the rail grips being twisted upon the rails will bind thereon and remain stationary so that the jack'acts to pull the tie toward the rail grips-until it arrives at its proper position. -Tt is pointed out that if during the operation of shifting a tie, a train approaches, these tie grips may be readily removed from the rails by simply striking a blow .there against in the proper direction, so that the gripping action is released, thus enabling the prevention 'of accidents or the necessity of stopping the approaching train.

For removing ties, the jack is applied, as

shown in Figure 1 of the drawings. A

plate "30 is placed over the end of the tie which is to be removed and the chain passed underneath the adjacent rail on opposite sides of'the tie andengaged with-the hook bolt32. The hook 23 of the'jack is engaged in this chain-at the center thereof and the tie'hook 16 of the jack is placed over the rail at the opposite side of the track. 'By

operation of the jack in this manner, the tie can be substantially half-way removed.

The chain 31 is then placed under theopposite 'railofthe track andin the notch 26 of the rack bar head 25 and the jack again operated to push the tie from beneath the rail. In replacing ties, the jack is employed in a similar manner, with the exception of I the fact that the operation above described 1s reversed. In order to separate rails to remove end posts or the like, rail grips are placed-on the rail at each side of the joint. The base of the jack engages one of these rail grips and the corresponding end of the other rail grip engages in the notch-26' of the head 25. To pull the ends of rails together, as when taking-kinks out of tracks or when applying fish plates thereto, the

. rail grips are applied in the same manner and the tie hook is placedover one of these rail grips,-whi1e the other is engaged byv the hook 23. l

It will be obvious that a'struct ure of this formed in the botto ment by a portion ofthe jack,

section of the jack character will greatly facilitate the work of laying, replacing or reballasting ties or rails. It will also be obvious that the strucmyself to such specific [structure except as hereinafter claimed. I claim r 1. In a track jack, a housing formed in base and upper: sections which are separable, a rack bar reciprocable through the housing and having a chainhook at its lower end and means upon the upper section of the housing'for engaging a tieor rail to hold 7 the jack against displacement with relation 7 thereto. 7 r 2. In a track jack, a housing formed in base and upper sections which are separable, a rack bar reciprocable through the housing and having a chain 'hookat its lower end, meansupon the upper section of'the housing [for engaging a tie or rail to hold the jack against displacement withrelation thereto and a forked head for said rack.
